Yeah, stability is more important than having a neutral pH. My tap runs at 7.8 and my tanks are 7.6 because of DW, but none of my species that prefer acidic water naturally have any problems thriving in it.
If you have wild caught or fragile species, then it may be time to consider some peat moss or bogwood, but I wouldn't worry about it too much. Like said, altering pH is more risky than keeping it steady, and most species will adapt just fine to higher or lower pH's than recommended
